Homeopathic software

First I hope I’m on the right forum. If not, please redirect me.

I am relatively new to the field of Homeopathy. My interest has shot up in the recent weeks when a homeopathic doctor cured me of a gastric problem that had been giving me problems for some time. I was amazed at how quickly that watery tasting solution worked. Now I want to learn more.

My specific question is which homeopathic Materia Medica and Repertory software packages should I get? I hope that isn’t too broad of a question to answer. I’ve looked at the different webpages about Mercurius, Radar, MacRepertory, Encyclopedia Homeopathica, and a couple of others, but I don’t really don’t know what I’m looking at. All the adds say they are the best, etc. So it’s all very confusing. If possible, I want the least expensive, of course, but I don’t want to sacrifice a good quality program because of the price being too high. However, I don’t want to foolishly buy something very expensive, if there is something less expensive that will serve me, for most practical purposes, just as well as the costly product. I’ve bought stuff that was very expensive in the past, only to realize later that another brand product was half price and it would have served me just as well had I bought it instead. I’m sure you know the feeling. Are there any places that sell reliable used software of this nature? Any bulletin boards? Any recommendations and possible experiences, pros and cons, etc, from any of you more experienced guys would certainly be appreciated to help get me started on the right foot in doing my homework, if you know what I mean. Thank You for your time and suggestions.
